“Occasionally I forget that I put my alarm on and make it go off. I'm always amazed by the quick response. It really makes me feel safe. And they're always very courteous and professional even though... I'm the one that messed up. I really appreciate ADT and the price is so reasonable.”

“We just bought our home and chose ADT to provide our security service. Due to a delay in our closing, the original scheduled appointment for installation was delayed for a week, but they were very understanding. Upon installation, we were guided through the use of the system and we discussed some external safety issues as well. Very professional and courteous! Highly recommended for peace of mind!”
Larry
Joplin, MO
“We have peace of mind since ADT is protecting our home. The system is very easy to use and we feel so protected both when home and away. Before ADT we had experienced several attempted break-ins as well as one robbery where our guns were taken. Since ADT no break-ins just peace.”
